I have owned a Sansui AU999 Amplifier/TU999 Tuner and Cerwin Vega 211R Speakers since 1973. About 1 year ago one of the amplifier channels started acting up, sometimes working/sometimes not. Recently the left channel went out totally, and now the remaining channel is fading/crackling, etc. I want to get it repaired but cannot find anyone in the Miami area that works on older amplifies/tuners. Someone suggested I post this in the Sansui forum so here I am. Any suggestions will be greatly appreciated.
